Hi,
I own a Dell OptiPlex GX240 which, when ACPI is disabled
but IO-APIC is enabled, shows very slow USB performance.
I thought that this could be related to IO-APIC and
tried to boot with "noapic" appended to the kernel
command line. This way the USB transfer speed returned
to normal values.
To make sure that noone else encounters a similar problem,
I have written a patch which includes an IO-APIC blacklist
and disables IO-APIC according to the blacklist.
I would like this patch to be merged into the main
tree. If there is any revision/correction that needs to
be done on the patch, please let me know.
I would appreciate any comments.
Thank you for your attention.
Regards,
- Tear
Note: The patch is appended and attached (in case
Yahoo wraps some lines.)

Well, it's almost certainly not the IO-APIC per se.
It's more likely to be some irq routing issue, where ACPI fixes up
something. Do you have diffs of 'dmesg' with and without ACPI?

Wouldn't this also disable the IOAPIC in the (working) ACPI+IOAPIC case?

Yes, it would. However, I wanted to make my addition
to the kernel generic so that other people with
problematic IO-APIC implementations can blacklist
their systems without checking whether ACPI is enabled
or not.
Thank you for your question/attention.

But that's just wrong. First off, all distro kernels come with ACPI on, so
the thing you're fixing is really just for somebody who compiles his own
kernel in a particular (and unusual/strange) configuration, and you're
making it _worse_ for everybody else.
And you're blacklisting it without even understaning _what_ is wrong. I
really think we should figure that part out first,

That's not the interesting part.
There's no way the IO-APIC itself "cant' work". That's a normal Intel
IO-APIC, it's fine. There's somethign else that causes things to not work,
properly, and the question is why.
So the APIC choice triggers some other bug that then ACPI fixes up.
>From the dmesg between "acpi=ht" and "acpi-force", the prime candidates
would seem to be:
ENABLING IO-APIC IRQs
-...TIMER: vector=0x31 apic1=0 pin1=2 apic2=0 pin2=0 # slow
+...TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1 # fine
and
-uhci_hcd 0000:00:1f.2: irq 19, io base 0x0000ff80 # slow
+uhci_hcd 0000:00:1f.2: irq 17, io base 0x0000ff80 # fine
(Interestingly, your *other* USB controller at 0:1f.4 gets assigned irq 18
in both cases).
Now, I doubt it's the timer, and the UHCI irq thing sounds more likely to
be a problem anyway, since it's USB that's slow, so it would be
interesting to hear whether:
acpi=force pci=routeirq
is still slow (it should enable ACPI, but then force the interrupt routing
to use the PIRQ table anyway).
Also, if you can figure out which USB ports are on the _other_ controller
(the one that gets irq 18 regardless of whether ACPI is on or off), it
would also be interesting to hear whether the camera is always fast (or
perhaps always slow) when connected to a part that is off that
controller..
Finally, I wonder why that particular box is marked with an "acpi=ht"
blacklisting in the first place. Rather than add a new blacklist, it migth
be better to remove an old (and perhaps incorrect) one.
That blacklist entry is _ancient_. It's entirely possible that it's just
bogus: we've had so many ACPI fixes since it was added, that it's quite
possible that the blacklist entry itself is bogus, and is the result of
some old ACPI bug that triggered on that entry.
The Dell GX240 entry was added by commit 68e4ad79294 in the historic Linux
archive:
Author: Len Brown <[email protected]>
Date: Sat Aug 9 15:00:59 2003 -0400
ACPI from 2.4:
build: add ACPI_HT, delete ACPI_HT_ONLY
boot: add acpi={force, off, ht}; delete "noht", "acpismp="
add DMI blacklist from UnitedLinux
and since it sounds like the machine _works_ with ACPI on, my real
preference would be to just remove the black-list entry.
In fact, I thought that patch already existed in the -mm tree?
Len - do you have any archives back from 2003 and earlier to indicate why
the Dell GX240 was blacklisted?
In fact, googling for this shows some other users saying that removing the
blacklist entry fixes things:
http://forums.fedoraforum.org/showthread.php?t=107291
and there is another report ("Lil_miss_linux") claiming that moving a USB
cardreader from one USB plug to another just "fixed" the issue they had.
So I'm doubly interested to hear whether maybe the camera works fine in
another USB port (which I'd guess is the one presumably connected to
irq18).

"add DMI blacklist from UnitedLinux". Lost in the mists of time, I expect.
I guess we can tag remove-dell-optiplex-gx240-from-the-acpi-blacklist.patch
as "backport to 2.6.22.x if it doesn't break anything in 2.6.23-rcX".

Yes, Tear sent the correct patch a while back, akpm picked it up, and i slurped
it into my tree just last night for 2.6.23:
http://git.kernel.org/?p=linux/kernel/git/lenb/linux-acpi-2.6.git;a=commit;h=4d2fafd17a325b3f4f5f9edb1211bc7f4c311269

Yep, it came to us in this Cset on 2003-08-09
http://linux.bkbits.net:8080/linux-2.6.11-stable/?PAGE=cset&REV=3f35b56btNYYpQfjOuQmiUdjSGFtWg
A young, impressionable maintainer, I'd been working on Linux for about 2 months.
I sync'd the workarounds from 2.4 into 2.5, and this particular one came
from the "UnitedLinux" tree.
My theory at the time was that SuSE had been most successful deploying ACPI,
and so upstream should benefit from their workarounds.
I later realized that this was a strategic mistake, as distro workarounds
often paper-over real bugs by addressing the symptom only.
A bunch of these entries were removed over time, and these days I add
DMI workarounds only when we are sure we have the root cause.

nope, this function is on on hardware IRQ 19 in both cases.
it just looks like IRQ 17 in the ACPI case due to this:
ACPI: PCI Interrupt 0000:00:1f.2[D] -> GSI 19 (level, low) -> IRQ 17
Totally bogus? Yes.
google "Kill IRQ compression"
But while I truly hate this particular hack and I've wanted it gone for a long time,
it doesn't appear to be related to the failure at hand -- it just makes
it more irritating to debug.

Mr. Torvalds,
The patch scans the DMI for "Dell OptiPlex GX240"
and disables IO-APIC only if such a system is detected.
It does not disable IO-APIC for other people.
In addition, Dell OptiPlex GX240 is (at least currently)
in the ACPI blacklist. So with a regular distro, one
gets IO-APIC and acpi=ht which causes USB transfers
to be very slow.
I have made an attempt to get Dell OptiPlex GX240
out of the ACPI blacklist. Please see:
http://marc.info/?t=117897881900001&r=1&w=2
Nevertheless, I am willing to modify the patch
to make IO-APIC work when ACPI is enabled. A
quick search pointed me to the variable named
"acpi_disabled". I can use this variable to
detect whether ACPI is enabled and disable
IO-APIC if it is not. Please see the
attached patch for such an implementation.
> And you're blacklisting it without even understaning _what_ is wrong. I
> really think we should figure that part out first,
I willing to put effort into figuring out what
is wrong. Please let me know if there is anything
I can do to further our information about this
problem. As I said before, I would be glad to
send to you the diff between any of the four
cases I mentioned in my previous e-mail to you.
Were you able to take a look at the dmesg
outputs in my previous e-mail?
Thank you for your attention.
Regards,
- Tear

I think you meant to suggest acpi=force plus "acpi=noirq", which will
cause all of ACPI except its interrupt routing code to run.
(similarly, "pci=noacpi" causes all of ACPI to run except its
interrupt code and PCI bus enumeration code)
pci=routeirq actually just goes and forces the interrupt routing
for all PCI devices to be set up before driver probe time
when it is normally done. This is a workaround for PCI drivers
that don't call pci_enable_device() to enable their IRQ.
In any case, it is possible that the assumption that IRQs
are broken on this box may be invalid. In the case of
the PCI interrupts above 15 on this box -- they are
all "hard coded" in the _PRT -- there is no run-time
interrupt link to program, Linux will always use the
same IRQ for each device and it has no choice in the matter
in ACPI mode. So the same is likely true in legacy mode.

When we talk about "fast" and "slow" here, what are we talking about?
What are the relative speeds?
I see uhci only in dmesg, I guess there is no ehci on this box?
Also, can you associate the physical ports on back and front
with the software drivers loaded by performing an operation
on the port and observing which line in /proc/interrupts increments?
do all of the USB interfaces tested have their own unshared
IRQ in /proc/interrupts?
thanks,
-Len
ps. there could still be some "ACPI magic" going on here.
We've seen motherboards that enable parts of USB based
on what OS they think they are running. Try
acpi=force acpi_os_name=Linux acpi_osi=
and if that makes USB go slow, that is proof
of where the magic lives.
Also, please capture the output from acpidump
and attach it to a bug report here:
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
If you don't have acpidump installed, you can get it
from pmtools here:

Hi,
I have created a bug report in bugzilla.kernel.org.
Here's the URL:
http://bugzilla.kernel.org/show_bug.cgi?id=8572
I have attached the output of acpidump to the bug

Let's continue our discussion there.
Thanks,
- Tear
